Title
(EN) RELAY WITH SPRING-BASED CONTACT SYSTEM
(FR) RELAIS AVEC SYSTÈME DE CONTACT À RESSORT
Abstract
(EN)
Relay with a spring-based contact system (3) includes at least two pairs of contacts (4, 5), each of which comprises one fixed contact piece (4.1; 5.1) and one contact piece (4.2; 5.2). The movable contact pieces (4.2; 5.2) are coupled with a slide (1). A planar contact piece carrier (7) extends in its longitudinal section along its longitudinal axis (7.3). The second end (7.2) of the contact piece carrier (7) is coupled with the slide (1). The movable contact pieces (4.2; 5.2) are arranged and are movable independently from each other. The fixed contact pieces (4.1, 5.1) are arranged transversely to the longitudinal axis (7.3). The spring-based contact system (3) has at least one lead contact (5) and one lag contact (4) and a geometric offset for delayed opening or closing of the at least two pairs of contacts (4, 5).

L'invention concerne un relais avec un système de contact à ressort (3) comprenant au moins deux paires de contacts (4, 5), dont chacun comprend une pièce de contact fixe (4,1 ; 5.1) et une pièce de contact (4.2 ; 5.2). Les pièces de contact mobiles (4.2 ; 5.2 ) sont couplées à un coulisseau (1). Un support de pièce de contact planaire (7) s'étend dans sa section longitudinale le long de son axe longitudinal (7.3). La seconde extrémité (7.2) du support de pièce de contact (7) est couplée au coulisseau (1). Les pièces de contact mobiles sont agencées et sont mobiles indépendamment l'une de l'autre. Les pièces de contact fixes (4.1, 5.1) sont disposées transversalement à l'axe longitudinal (7.3). Le système de contact à ressort (3) présente au moins un contact d'avance (5) et un contact de retard (4) et un décalage géométrique pour l'ouverture ou la fermeture retardée des deux paires de contacts (4, 5).
